ABSTRACT: Previous studies have shown that coal over-lain by a thick sequence of nonmarine strata is generally lower in sulfur content than adjacent areas of the same seam overlain by marine strata. These nonmarine sedi-ments are interpreted to be of fluvial origin and consist primarily of crevasse-splay deposits. Two patterns of occurrence of crevasse-splay deposits associated with low-sulfur coal have been recognized in the Pennsylvanian rocks of Illinois. These are (1) localized splay deposits distributed at intervals along the trend of rivers that flowed through the peat swamp, and (2) clusters of splay deposits which are part of a deltaic lobe that prograded over the peat swamp. Both types of deposits are repre-sented in the stratigrap...
